[RFC 17/24] drm/msm/dsi: make save_state/restore_state callbacks accept msm_dsi_phy
Dmitry Baryshkov

Mon Mar 1 23:25:00 UTC 2021
Make save_state/restore callbacks accept struct msm_dsi_phy rather than
struct msm_dsi_pll. This moves them to struct msm_dsi_phy_ops, allowing
us to drop struct msm_dsi_pll_ops.
